Rechyyy says in his description of the video that he was invited to EA to play an early build of Dragon Age: Inquistion, and it was running on PC at max settings. It appears he was playing the game using an Xbox controller, so for any PC keyboard and mouse purists sadly you won't be seeing any PC UI here.

It's worth noting that most footage we've seen of the game up to now will probably be running on a PC anyway, but this new video below shows some different locations and combat at least.
